Cat5e at 500 feet and moveable

February 25, 2009 at 05:22:37
Specs: Windows XP
I need to install/replace existing phone line on a moveable Lift bridge. We will be installing a T1 line. Cat5e stranded cable appears to be the cable of choice. Will there be any performance loss for live streaming video? Do we need to install a repeater or switch midway? Is this the right cable?

ethernet won't go 500 ft. You need a repeater after the first 328ft.

A T1 for a mechanical device? You really need 1.5mbps for that operation?

This bridge has video cameras, phone lines and have plans to remotely operate.

I wouldn't exceed 85% of the maximum segment length of that Cat5e. The maximum length being 100 m or 328 feet.

I've found that once you exceed 85% you risk attenuation and signal degradation. If you split the difference and put your repeater at the halfway point, everything should work fine.

I don't know anything at all about your budget, but if it were me and budget allowed, I'd be looking seriously at a fibre optic solution considering the distance and usage.

then you will need a T1. Consider running fiber instead of cat5. You can go the distance you want with fiber

T1 needs a csu and dsu unit. It is not ethernet cable. You should use T1 cable. 2 runs of cat 5 might work.

Fiber might be eaaier.
